International data used to mean either paying outrageous roaming fees or going offline. The options have improved, but choosing wrong still costs money or causes headaches.
eSIM Has Changed Everything
If your phone supports eSIM, you can buy international data plans instantly through apps. No physical card to swap, no hunting for SIM vendors on arrival. Activate before you land and you’re connected.
Prices have dropped dramatically. A week of data in Europe might cost $5-15 through eSIM providers, compared to carrier roaming at dollars per megabyte.
When Physical SIMs Still Win
Not all phones support eSIM. Older models need physical cards. Some eSIM providers have limited coverage in specific regions. Physical SIMs from local carriers often have better rates and coverage.
Airport vendors are convenient but overpriced. Neighborhood phone shops in most countries sell tourist SIMs cheaper. The time trade-off depends on your priorities.
WiFi Hunting
Free WiFi remains common but unreliable. Cafes, hotels, and some public spaces offer it. Plan for gaps in coverage rather than assuming constant access.
WiFi calling through your home carrier can use foreign networks without roaming charges. Make sure it’s enabled before you leave.
Offline Preparation
Download maps, translation packs, and essential documents before traveling. If connectivity fails, you have backups. This preparation takes minutes and saves potential disasters.
Identify which apps work offline. Some navigation apps require connectivity; others function independently. Test before depending on them.
VPN Considerations
Public WiFi security remains questionable. A VPN encrypts your traffic, protecting banking and personal information. Some countries restrict VPN use, so check regulations at your destination.
